LAWN-*SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 650,835, dated June 5, 1900.

Application filed August 12, 1899. Serial No. 726,974. (No model.)

To all whom it may concern.-

: Be it known that I, JAMES ALSTON HARMON, a citizen of the United States, residing at Hawkinsville, in the county of Pulaski and State of Georgia, have invented a new and useful Lawn-Sprinkler, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

Figure 1 is a vertical section of the entire machine. Fig. 2 is a view of the paddlewheel when removed from the other parts of the machine.

In Fig. 1 the tapering stafi comes to a sharp point at the lower end to hold the sprinkler firmly in the ground when in use. The upper end at G has small hole with threads for holding the paddle-wheelin place. From the top the stafi tapers downward to shoulder. Below the shoulder, running down for an inch or more, are threads cut on staif. The purpose of the threads is to hold in position the T-shaped tubing or casing. (See G F, Fig. 1.) The further object of these threads is to form an adjustment for the regulating of the volume of water by running the casing up or down, and thus enlarging the opening at the top of casing or T-tube.

As seen in Fig. 1, the lower end of the tube or casing screws onto the staff at the shoulder, thus making adjustment spoken of above. The top of casing is open to allow the passage of the water upward. The end at right angles F is screwed into the hose through which comes the supply of water.

Fig. 2 represents the paddle -wheel, the arms of which are twisted to an angle of about forty-five degrees, as in case of windmill, in the center of which is an eye or bearing, and it is mounted on top of staff at G by suitable bearings. Thus the water coming through hose and through tube-casing at F rushes out at the top, striking the paddle-wheel, setting it in rapid motion, and the quick revolutions of the paddle-wheel distribute the water for a space of many feet in diameter. It is ap parent that any number of these may be grouped together, thus forming combinations.

These lawn-sprinklers are to be made of suitable metals. 4

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A lawn-sprinkler, comprising an upright staff, tapering to a point at its lower end and diminishing from its upper end to shoulder H J, and provided with threads from said shoulder downward, to receive and hold in position a casing T, and for the purpose of regulating the flow of water, substantially as described.

2. Alawn-sprinkler, comprising an upright staff, on which is mounted T-casing by means of a thread in lower end of said casing answering to threads on the staff by which the casing is firmly held in position and by which the flow of the water is regulated and the character of the spray determined, the end of the casing at right angles to main stem be ing threaded for the adjustment of hose and the upper end of said casing receiving the upper end of stafi with sufficient space between them to allow the passage of water outward the quantity being determined by screwing casing up or downon staff substantially as described.

3. A lawn-sprinkler,comprising an upright stafi on which is mounted a T-casing with suitable adjustments above which and on the top of said staif is mounted a paddle-wheel by means of a screw passing through center of paddle-wheel and into center of upper end of staff, said paddle-wheel having arms thin and flat and twisted to suitable angle, sub stantially as described.
